--- stage: Enablement group: Geo info: To determine the technical writer assigned to the Stage/Group associated with this page, see https://about.gitlab.com/handbook/engineering/ux/technical-writing/#designated-technical-writers type: howto --- # Version specific update instructions Check this document if it includes instructions for the version you are updating. These steps go together with the [general steps](updating_the_geo_nodes.md#general-update-steps) for updating Geo nodes. ## Updating to GitLab 12.9 CAUTION: **Warning:** GitLab 12.9.0 through GitLab 12.9.3 are affected by [a bug that stops repository verification](https://gitlab.com/gitlab-org/gitlab/-/issues/213523). The issue is fixed in GitLab 12.9.4. Please upgrade to GitLab 12.9.4 or later. ## Updating to GitLab 12.7 DANGER: **Danger:** Only upgrade to GitLab 12.7.5 or later. Do not upgrade to versions 12.7.0 through 12.7.4 because there is [an initialization order bug](https://gitlab.com/gitlab-org/gitlab/-/issues/199672) that causes Geo **secondaries** to set the incorrect database connection pool size. [The fix](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/24021) was shipped in 12.7.5. ## Updating to GitLab 12.2 GitLab 12.2 includes the following minor PostgreSQL updates: - To version `9.6.14` if you run PostgreSQL 9.6. - To version `10.9` if you run PostgreSQL 10. This update will occur even if major PostgreSQL updates are disabled. Before [refreshing Foreign Data Wrapper during a Geo upgrade](https://docs.gitlab.com/omnibus/update/README.html#run-post-deployment-migrations-and-checks), restart the Geo tracking database: ```shell sudo gitlab-ctl restart geo-postgresql ``` The restart avoids a version mismatch when PostgreSQL tries to load the FDW extension. ## Updating to GitLab 12.1 By default, GitLab 12.1 will attempt to automatically update the embedded PostgreSQL server to 10.7 from 9.6. Please see [the omnibus documentation](https://docs.gitlab.com/omnibus/settings/database.html#upgrading-a-geo-instance) for the recommended procedure. This can be temporarily disabled by running the following before updating: ```shell sudo touch /etc/gitlab/disable-postgresql-upgrade ``` ## Updating to GitLab 12.0 CAUTION: **Warning:** This version is affected by [a bug that results in new LFS objects not being replicated to Geo secondary nodes](https://gitlab.com/gitlab-org/gitlab/-/issues/32696). The issue is fixed in GitLab 12.1. Please upgrade to GitLab 12.1 or later. ## Updating to GitLab 11.11 CAUTION: **Warning:** This version is affected by [a bug that results in new LFS objects not being replicated to Geo secondary nodes](https://gitlab.com/gitlab-org/gitlab/-/issues/32696). The issue is fixed in GitLab 12.1. Please upgrade to GitLab 12.1 or later. ## Updating to GitLab 10.8 Before 10.8, broadcast messages would not propagate without flushing the cache on the **secondary** nodes. This has been fixed in 10.8, but requires one last cache flush on each **secondary** node: ```shell sudo gitlab-rake cache:clear ``` ## Updating to GitLab 10.6 In 10.4, we started to recommend that you define a password for database user (`gitlab`). We now require this change as we use this password to enable the Foreign Data Wrapper, as a way to optimize the Geo Tracking Database. We are also improving security by disabling the use of **trust** authentication method. 1. **(primary)** Login to your **primary** node and run: ```shell gitlab-ctl pg-password-md5 gitlab # Enter password: # Confirm password: # fca0b89a972d69f00eb3ec98a5838484 ``` Copy the generated hash and edit `/etc/gitlab/gitlab.rb`: ```ruby # Fill with the hash generated by `gitlab-ctl pg-password-md5 gitlab` postgresql['sql_user_password'] = '' # Every node that runs Unicorn or Sidekiq needs to have the database # password specified as below. # This must be present in all application nodes. gitlab_rails['db_password'] = '' ``` Still in the configuration file, locate and remove the `trust_auth_cidr_address`: ```ruby postgresql['trust_auth_cidr_addresses'] = ['127.0.0.1/32','1.2.3.4/32'] # <- Remove this ``` 1. **(primary)** Reconfigure and restart: ```shell sudo gitlab-ctl reconfigure sudo gitlab-ctl restart ``` 1. **(secondary)** Login to all **secondary** nodes and edit `/etc/gitlab/gitlab.rb`: ```ruby # Fill with the hash generated by `gitlab-ctl pg-password-md5 gitlab` postgresql['sql_user_password'] = '' # Every node that runs Unicorn or Sidekiq needs to have the database # password specified as below. # This must be present in all application nodes. gitlab_rails['db_password'] = '' # Enable Foreign Data Wrapper geo_secondary['db_fdw'] = true # Secondary address in CIDR format, for example '5.6.7.8/32' postgresql['md5_auth_cidr_addresses'] = ['/32'] ``` Still in the configuration file, locate and remove the `trust_auth_cidr_address`: ```ruby postgresql['trust_auth_cidr_addresses'] = ['127.0.0.1/32','5.6.7.8/32'] # <- Remove this ``` 1. **(secondary)** Reconfigure and restart: ```shell sudo gitlab-ctl reconfigure sudo gitlab-ctl restart ``` ## Updating to GitLab 10.5 For Geo Disaster Recovery to work with minimum downtime, your **secondary** node should use the same set of secrets as the **primary** node. However, setup instructions prior to the 10.5 release only synchronized the `db_key_base` secret. To rectify this error on existing installations, you should **overwrite** the contents of `/etc/gitlab/gitlab-secrets.json` on each **secondary** node with the contents of `/etc/gitlab/gitlab-secrets.json` on the **primary** node, then run the following command on each **secondary** node: ```shell sudo gitlab-ctl reconfigure ``` If you do not perform this step, you may find that two-factor authentication [is broken following DR](../disaster_recovery/index.md#i-followed-the-disaster-recovery-instructions-and-now-two-factor-auth-is-broken). To prevent SSH requests to the newly promoted **primary** node from failing due to SSH host key mismatch when updating the **primary** node domain's DNS record you should perform the step to [Manually replicate **primary** SSH host keys](configuration.md#step-2-manually-replicate-the-primary-nodes-ssh-host-keys) in each **secondary** node. ## Updating to GitLab 10.3 ### Support for SSH repository synchronization removed In GitLab 10.2, synchronizing secondaries over SSH was deprecated. In 10.3, support is removed entirely. All installations will switch to the HTTP/HTTPS cloning method instead. Before updating, ensure that all your Geo nodes are configured to use this method and that it works for your installation. In particular, ensure that [Git access over HTTP/HTTPS is enabled](configuration.md#step-6-enable-git-access-over-httphttps). Synchronizing repositories over the public Internet using HTTP is insecure, so you should ensure that you have HTTPS configured before updating. Note that file synchronization is **also** insecure in these cases! ## Updating to GitLab 10.2 ### Secure PostgreSQL replication Support for TLS-secured PostgreSQL replication has been added. If you are currently using PostgreSQL replication across the open internet without an external means of securing the connection (e.g., a site-to-site VPN), then you should immediately reconfigure your **primary** and **secondary** PostgreSQL instances according to the [updated instructions](database.md). If you *are* securing the connections externally and wish to continue doing so, ensure you include the new option `--sslmode=prefer` in future invocations of `gitlab-ctl replicate-geo-database`. ### HTTPS repository sync Support for replicating repositories and wikis over HTTP/HTTPS has been added. Replicating over SSH has been deprecated, and support for this option will be removed in a future release. To switch to HTTP/HTTPS replication, log into the **primary** node as an admin and visit **{admin}** **Admin Area >** **{location-dot}** **Geo** (`/admin/geo/nodes`). For each **secondary** node listed, press the "Edit" button, change the "Repository cloning" setting from "SSH (deprecated)" to "HTTP/HTTPS", and press "Save changes". This should take effect immediately. Any new secondaries should be created using HTTP/HTTPS replication - this is the default setting. After you've verified that HTTP/HTTPS replication is working, you should remove the now-unused SSH keys from your secondaries, as they may cause problems if the **secondary** node if ever promoted to a **primary** node: 1. **(secondary)** Login to **all** your **secondary** nodes and run: ```ruby sudo -u git -H rm ~git/.ssh/id_rsa ~git/.ssh/id_rsa.pub ``` ### Hashed Storage CAUTION: **Warning:** Hashed storage is in **Alpha**. It is considered experimental and not production-ready. See [Hashed Storage](../../repository_storage_types.md) for more detail. If you previously enabled Hashed Storage and migrated all your existing projects to Hashed Storage, disabling hashed storage will not migrate projects to their previous project based storage path. As such, once enabled and migrated we recommend leaving Hashed Storage enabled. ## Updating to GitLab 10.1 CAUTION: **Warning:** Hashed storage is in **Alpha**. It is considered experimental and not production-ready. See [Hashed Storage](../../repository_storage_types.md) for more detail. [Hashed storage](../../repository_storage_types.md) was introduced in GitLab 10.0, and a [migration path](../../raketasks/storage.md) for existing repositories was added in GitLab 10.1. ## Updating to GitLab 10.0 Since GitLab 10.0, we require all **Geo** systems to [use SSH key lookups via the database](../../operations/fast_ssh_key_lookup.md) to avoid having to maintain consistency of the `authorized_keys` file for SSH access. Failing to do this will prevent users from being able to clone via SSH. Note that in older versions of Geo, attachments downloaded on the **secondary** nodes would be saved to the wrong directory. We recommend that you do the following to clean this up. On the **secondary** Geo nodes, run as root: ```shell mv /var/opt/gitlab/gitlab-rails/working /var/opt/gitlab/gitlab-rails/working.old mkdir /var/opt/gitlab/gitlab-rails/working chmod 700 /var/opt/gitlab/gitlab-rails/working chown git:git /var/opt/gitlab/gitlab-rails/working ``` You may delete `/var/opt/gitlab/gitlab-rails/working.old` any time. Once this is done, we advise restarting GitLab on the **secondary** nodes for the new working directory to be used: ```shell sudo gitlab-ctl restart ``` ## Updating from GitLab 9.3 or older If you started running Geo on GitLab 9.3 or older, we recommend that you resync your **secondary** PostgreSQL databases to use replication slots. If you started using Geo with GitLab 9.4 or 10.x, no further action should be required because replication slots are used by default. However, if you started with GitLab 9.3 and updated later, you should still follow the instructions below. When in doubt, it does not hurt to do a resync. The easiest way to do this in Omnibus is the following: 1. Make sure you have Omnibus GitLab on the **primary** server. 1. Run `gitlab-ctl reconfigure` and `gitlab-ctl restart postgresql`. This will enable replication slots on the **primary** database. 1. Check the steps about defining `postgresql['sql_user_password']`, `gitlab_rails['db_password']`. 1. Make sure `postgresql['max_replication_slots']` matches the number of **secondary** Geo nodes locations. 1. Install GitLab on the **secondary** server. 1. Re-run the [database replication process](database.md#step-3-initiate-the-replication-process). ## Updating to GitLab 9.0 > **IMPORTANT**: With GitLab 9.0, the PostgreSQL version is updated to 9.6 and manual steps are required in order to update the **secondary** nodes and keep the Streaming Replication working. Downtime is required, so plan ahead. The following steps apply only if you update from a 8.17 GitLab version to 9.0+. For previous versions, update to GitLab 8.17 first before attempting to update to 9.0+. --- Make sure to follow the steps in the exact order as they appear below and pay extra attention in what node (either **primary** or **secondary**) you execute them! Each step is prepended with the relevant node for better clarity: 1. **(secondary)** Log in to **all** your **secondary** nodes and stop all services: ```ruby sudo gitlab-ctl stop ``` 1. **(secondary)** Make a backup of the `recovery.conf` file on **all** **secondary** nodes to preserve PostgreSQL's credentials: ```shell sudo cp /var/opt/gitlab/postgresql/data/recovery.conf /var/opt/gitlab/ ``` 1. **(primary)** Update the **primary** node to GitLab 9.0 following the [regular update docs](../../../update/README.md). At the end of the update, the **primary** node will be running with PostgreSQL 9.6. 1. **(primary)** To prevent a de-synchronization of the repository replication, stop all services except `postgresql` as we will use it to re-initialize the **secondary** node's database: ```shell sudo gitlab-ctl stop sudo gitlab-ctl start postgresql ``` 1. **(secondary)** Run the following steps on each of the **secondary** nodes: 1. **(secondary)** Stop all services: ```shell sudo gitlab-ctl stop ``` 1. **(secondary)** Prevent running database migrations: ```shell sudo touch /etc/gitlab/skip-auto-migrations ``` 1. **(secondary)** Move the old database to another directory: ```shell sudo mv /var/opt/gitlab/postgresql{,.bak} ``` 1. **(secondary)** Update to GitLab 9.0 following the [regular update docs](../../../update/README.md). At the end of the update, the node will be running with PostgreSQL 9.6. 1. **(secondary)** Make sure all services are up: ```shell sudo gitlab-ctl start ``` 1. **(secondary)** Reconfigure GitLab: ```shell sudo gitlab-ctl reconfigure ``` 1. **(secondary)** Run the PostgreSQL upgrade command: ```shell sudo gitlab-ctl pg-upgrade ``` 1. **(secondary)** See the stored credentials for the database that you will need to re-initialize the replication: ```shell sudo grep -s primary_conninfo /var/opt/gitlab/recovery.conf ``` 1. **(secondary)** Save the snippet below in a file, let's say `/tmp/replica.sh`. Modify the embedded paths if necessary: ```shell #!/bin/bash PORT="5432" USER="gitlab_replicator" echo --------------------------------------------------------------- echo WARNING: Make sure this script is run from the secondary server echo --------------------------------------------------------------- echo echo Enter the IP or FQDN of the primary PostgreSQL server read HOST echo Enter the password for $USER@$HOST read -s PASSWORD echo Enter the required sslmode read SSLMODE echo Stopping PostgreSQL and all GitLab services sudo service gitlab stop sudo service postgresql stop echo Backing up postgresql.conf sudo -u postgres mv /var/opt/gitlab/postgresql/data/postgresql.conf /var/opt/gitlab/postgresql/ echo Cleaning up old cluster directory sudo -u postgres rm -rf /var/opt/gitlab/postgresql/data echo Starting base backup as the replicator user echo Enter the password for $USER@$HOST sudo -u postgres /opt/gitlab/embedded/bin/pg_basebackup -h $HOST -D /var/opt/gitlab/postgresql/data -U gitlab_replicator -v -x -P echo Writing recovery.conf file sudo -u postgres bash -c "cat > /var/opt/gitlab/postgresql/data/recovery.conf <<- _EOF1_ standby_mode = 'on' primary_conninfo = 'host=$HOST port=$PORT user=$USER password=$PASSWORD sslmode=$SSLMODE' _EOF1_ " echo Restoring postgresql.conf sudo -u postgres mv /var/opt/gitlab/postgresql/postgresql.conf /var/opt/gitlab/postgresql/data/ echo Starting PostgreSQL sudo service postgresql start ``` 1. **(secondary)** Run the recovery script using the credentials from the previous step: ```shell sudo bash /tmp/replica.sh ``` 1. **(secondary)** Reconfigure GitLab: ```shell sudo gitlab-ctl reconfigure ``` 1. **(secondary)** Start all services: ```shell sudo gitlab-ctl start ``` 1. **(secondary)** Repeat the steps for the remaining **secondary** nodes. 1. **(primary)** After all **secondary** nodes are updated, start all services in **primary** node: ```shell sudo gitlab-ctl start ``` ### Update tracking database on **secondary** node After updating a **secondary** node, you might need to run migrations on the tracking database. The tracking database was added in GitLab 9.1, and it is required since 10.0. 1. Run database migrations on tracking database: ```shell sudo gitlab-rake geo:db:migrate ``` 1. Repeat this step for each **secondary** node.
